Description

Technical Field

[0001] The present invention relates to the technical field of TSC1 request processing, and in particular to an arbitration method, controller and medium for TSC1 requests. Background Art

[0002] In the commercial vehicle sector, automotive electrical and electronic architecture has traditionally followed a distributed "one controller per function" model. However, with the advancement of automotive electronics technology, this distributed architecture has evolved towards a domain-based architecture, resulting in the emergence of body, powertrain, and chassis domain controllers responsible for different vehicle components. The powertrain domain controller receives numerous TSC1 requests from external controllers, which it then arbitrates, selecting the most important ones for execution to avoid confusion.

[0003] Application number CN200610025338.8 discloses a bus arbitration method for a bus arbitration system. The system has a first priority and a second priority, with the first priority being higher than the second. When the system detects a second-priority request followed by a first-priority request, it raises the priority of the second-priority request to the first priority. This arbitration scheme is unsuitable for TSC1 request arbitration in commercial vehicle domain control architectures. Furthermore, with only two levels of priority, there's no way to handle multiple first- or second-level requests, which can easily lead to arbitration confusion. Summary of the Invention

[0004] In order to solve the above technical problem or at least partially solve the above technical problem, the present invention provides an arbitration method and design method for TSC1 request.

[0005] In a first aspect, the present invention provides an arbitration method for a TSC1 request, comprising: parsing a received TSC1 request message to obtain request information including a source address of the TSC1 request message, a TSC1 request mode, a priority, a speed, and a torque;

[0006] Different types of TSC1 requests are screened out according to the request information, and corresponding types of TSC1 requests are arbitrated using a preset arbitration strategy: the screened speed control request and torque control request are arbitrated using the control request arbitration strategy; the screened speed limit request and positive torque limit request are arbitrated using the positive limit request arbitration strategy; and the screened negative torque limit request is arbitrated using the negative limit request arbitration strategy;

[0007] Finally, the winning control request and / or restriction request is further arbitrated through the control and restriction arbitration strategy.

[0008] Furthermore, the TSC1 request message of the external controller includes: DE message and DR message of the retarder controller, AE message, AR message and AEBSE message of the EBS controller, ACCE message and ACCR message of the cruise controller, TE message and TR message of the transmission controller, VE message and VR message of the vehicle controller, and PE message of the power take-off controller.

[0009] Furthermore, the control request arbitration strategy includes:

[0010] When there is only one torque control request or speed control request, the control request wins;

[0011] When there are multiple torque control requests or speed control requests, the control request with a higher priority is determined to be the winner; if the priority cannot determine the winning control request, then for the torque control request, based on the priority, the winning torque control request is determined according to the torque value type, sequence, torque value size and custom priority; for the speed control request, based on the priority, the winning speed control request is determined according to the sequence, speed value size and custom priority; for the winning torque control request and the winning speed control request, it is determined that the one with the higher custom priority ultimately wins.

[0012] Furthermore, for torque control requests, based on the priority, the winning torque control request is determined according to the torque value type, sequence, torque value and custom priority, including:

[0013] When multiple torque control requests have the same priority, the torque control request with a positive torque value is determined to win compared with the torque control request with a negative torque value; when the priorities are the same and the torque value type cannot determine the winning torque control request, the earlier torque control request is determined to win according to the order of the torque control requests; when the priorities are the same and the torque value type and order cannot determine the winning torque control request, the torque control request with a larger torque value is determined to win; when the priorities are the same and the torque value type, order and torque value cannot determine the winning torque control request, the torque control request with a higher custom priority is determined to win according to the custom priority set for the message sent to the external controller.

[0014] Furthermore, for the speed control request, on the basis of priority, the winning speed control request is determined according to the order, speed value and custom priority, including: when there are multiple speed control requests and the priority is the same, the speed control request that comes first is determined to be the winner according to the order of the speed control requests; when the priority is the same and the order of the speed control requests cannot determine the winning speed control request, the speed control request with the larger speed value is determined to be the winner; when the priority is the same and the order of the speed control requests and the speed value cannot determine the winning speed control request, the speed control request with the higher custom priority is determined to be the winner.

[0015] Furthermore, the positive restriction request arbitration strategy includes:

[0016] When there is only one positive torque limit request, the positive torque limit request wins;

[0017] When there are multiple positive torque limit requests, the positive torque limit request with the highest priority wins;

[0018] When the priorities are the same and the winning positive torque limit request cannot be determined among the simultaneous positive torque limit requests, the positive torque limit request with the smaller torque value is determined to be the winner; when the priorities and torque values ​​are the same and the winning positive torque limit request cannot be determined, the speed control request with the higher user-defined priority is determined to be the winner;

[0019] When there are multiple speed limit requests, the speed limit request with the highest priority wins;

[0020] When the priorities are the same and the winning speed limit request cannot be determined among the simultaneous speed limit requests, the speed limit request with the smaller speed value is determined to be the winner; when the priorities and speed values ​​are the same and the winning speed limit request cannot be determined, the speed limit request with the higher customized priority is determined to be the winner;

[0021] The torque and speed limited by the winning torque limit request and the winning speed limit request are output.

[0022] Furthermore, the negative limit request arbitration strategy includes:

[0023] When there is only one negative torque limit request, the negative torque limit request wins;

[0024] When there are multiple negative torque limit requests, the negative torque limit request with the highest priority wins;

[0025] When the priority is the same and the winning negative torque limit request cannot be determined among the simultaneous negative torque requests, the negative torque limit request with the larger torque value is determined to be the winner. When the priority and torque value are the same and the winning negative torque limit request cannot be determined, the speed limit request with the higher customized priority is determined to be the winner.

[0026] Furthermore, the control and restriction arbitration strategy includes:

[0027] If there is no torque control request or speed control request, in the speed limit state, the maximum speed is limited by the winning speed limit request in the positive limit arbitration strategy, the maximum limit torque is limited by the winning positive torque limit request in the positive limit arbitration strategy, and the minimum limit torque is limited by the winning negative torque limit request in the negative limit arbitration strategy;

[0028] If there is torque control, the speed is limited, the maximum speed is the preset value, and the output torque is limited by the winning torque control request in the control request arbitration strategy;

[0029] If there is speed control, in the speed control state, the control speed target value is limited by the winning speed control request in the control request arbitration strategy, and the maximum limit torque is limited by the winning positive torque limit request in the positive limit arbitration strategy; the minimum limit torque is 0.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0045] It should be noted that, in this document, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0046] Example 1

[0047] An embodiment of the present invention provides an arbitration method for a TSC1 request, including:

[0048] S100: The power domain controller receives a TSC1 request message from an external controller via the CAN message bus. The TSC1 request message includes: a DE message and a DR message from the retarder controller; AE messages, AR messages, and AEBSE messages from the EBS controller; ACCE messages and ACCR messages from the cruise controller; TE messages and TR messages from the transmission controller; VE messages and VR messages from the vehicle controller; and a PE message from the power take-off controller.

[0049] S200 , the power domain controller parses the TSC1 request message to obtain request information including the source address of the TSC1 request message, the TSC1 request mode, the priority, the rotation speed, and the torque.

[0050] S300 , filtering out different types of TSC1 requests based on the request information. The TSC1 requests include control requests and limit requests, wherein the control requests include speed control requests and torque control requests, and the limit requests include speed limit requests, positive torque limit requests, and negative torque limit requests.

[0051] See Figure 2 As shown, the TSC1 request of the corresponding type is arbitrated through the preset arbitration strategy:

[0052] S310 , arbitrating the filtered speed control request and torque control request using a control request arbitration strategy.

[0053] In the specific implementation process, please refer to Figure 4 As shown, the control request arbitration strategy includes:

[0054] When there is only one of the torque control request or the speed control request, the control request wins.

[0055] When there are a plurality of the torque control requests or the speed control requests, it is determined that the control request with the highest priority wins.

[0056] If the priority level cannot determine a winning control request, then for the torque control request, the winning torque control request is determined based on the priority level, the torque value type, priority order, torque value size, and custom priority level. Specifically, if multiple torque control requests have the same priority level, the torque control request with a positive torque value is determined to be the winning torque control request over the torque control request with a negative torque value. If the priorities are the same and the torque value type cannot determine the winning torque control request, the earlier torque control request is determined to be the winning torque control request based on the priority level of the torque control requests. If the priorities are the same and the torque value type and priority order cannot determine the winning torque control request, the torque control request with the larger torque value is determined to be the winning torque control request. If the priorities are the same and the torque value type, priority order, and torque value size cannot determine the winning torque control request, the torque control request with the higher custom priority level is determined to be the winning torque control request.

[0057] Among them, see Figure 3 As shown, the custom priority is set according to the message sent to the external controller, and is used to indicate the priority of different request messages sent by different external controllers. For example, in a preferred custom priority division method, the custom priority value of the AE message and AR message of the EBS controller is set to 0, the custom priority value of the DE message and DR message of the retarder controller is set to 1, the custom priority value of the PE message of the power take-off controller is set to 2, the custom priority value of the TE message and TR message of the transmission controller is set to 3, the custom priority value of the VE message and VR message of the vehicle controller is set to 4, the custom priority value of the ACCE message and ACCR message of the cruise controller is set to 5, and the priority value of the AEBSE message of the EBS controller is set to 6.

[0058] If the priority levels cannot determine a winning control request, the winning speed control request is determined based on the priority, order of precedence, speed value, and custom priority. Specifically, if there are multiple speed control requests with the same priority, the first speed control request is determined to be the winning speed control request based on the order of precedence. If the priorities are the same and the order of precedence cannot determine the winning speed control request, the speed control request with the higher speed value is determined to be the winning speed control request. If the priorities are the same and the order of precedence and speed value cannot determine the winning speed control request, the speed control request with the higher custom priority is determined to be the winning speed control request.

[0059] For the winning torque control request and the winning speed control request, it is determined that the one with the higher customized priority ultimately wins.

[0060] A winning speed control request or torque control request is output through a control request arbitration strategy. The control request arbitration strategy coordinates torque and speed control requests from the external controller. If the speed control request ultimately wins after arbitration, the output speed is limited; if the torque control request ultimately wins after arbitration, the output torque is limited.

[0061] S320 : Arbitrate the filtered rotational speed limit request and positive torque limit request using a positive limit request arbitration strategy.

[0062] In the specific implementation process, please refer to Figure 5 As shown, the positive restriction request arbitration strategy includes:

[0063] When there is only one positive torque limit request or speed limit request, that limit request wins;

[0064] When there are multiple positive torque limit requests, the positive torque limit request with the higher priority is determined to be the winner; when the priorities are the same and the winning positive torque limit request cannot be determined among the simultaneous positive torque limit requests, the positive torque limit request with the smaller torque value is determined to be the winner; when the priorities and torque values ​​are the same and the winning positive torque limit request cannot be determined, the speed control request with the higher custom priority is determined to be the winner;

[0065] When there are multiple speed limit requests, the speed limit request with the higher priority is determined to be the winner; when the priorities are the same and the winning speed limit request cannot be determined among the simultaneous speed limit requests, the speed limit request with the smaller speed value is determined to be the winner; when the priorities and speed values ​​are the same and the winning speed limit request cannot be determined, the speed limit request with the higher custom priority is determined to be the winner;

[0066] The maximum output torque and the maximum output speed limited by the winning torque limit request and the winning speed limit request are output.

[0067] The main function of the positive limit request arbitration strategy is to coordinate the positive torque limit request and speed limit request from the external controller. After arbitration, the winning torque limit request and the winning speed limit request limit the maximum output torque and the maximum output speed respectively.

[0068] S330 : Arbitrating the filtered negative torque limit requests using a negative limit request arbitration strategy.

[0069] In the specific implementation process, please refer to Figure 6 As shown, the negative limit request arbitration strategy includes:

[0070] When there is only one negative torque limit request, the negative torque limit request wins;

[0071] When there are multiple negative torque limit requests, the negative torque limit request with the highest priority wins;

[0072] When the priority is the same and the winning negative torque limit request cannot be determined among the simultaneous negative torque requests, the negative torque limit request with the larger torque value is determined to be the winner. When the priority and torque value are the same and the winning negative torque limit request cannot be determined, the speed limit request with the higher customized priority is determined to be the winner.

[0073] The negative torque limit request arbitration strategy is mainly to coordinate the negative torque limit request from the external controller. The winning negative torque limit request after arbitration limits the minimum output torque.

[0074] S340 , finally, the winning control request and / or restriction request is further arbitrated using a control and restriction arbitration strategy.

[0075] In the specific implementation process, please refer to Figure 7 As shown, the control and restriction arbitration strategy includes:

[0076] If there is no winning torque control request or speed control request, the speed control state is 0 (indicating no speed control), that is, it is in the speed limit state. The maximum speed in the speed limit state is limited by the winning speed limit request in the positive limit arbitration strategy, the maximum limit torque is limited by the winning positive torque limit request in the positive limit arbitration strategy, and the minimum limit torque is limited by the winning negative torque limit request in the negative limit arbitration strategy.

[0077] If there is a winning torque control request, the speed control state is 0, that is, it is in the speed limit state. The maximum speed in the speed limit state is the preset value (the preset value is set to 8192rpm), and the output torque is limited by the winning torque control request in the control request arbitration strategy, and the maximum limit torque and the minimum limit torque are the same as the output torque.

[0078] If there is a winning speed control request, the speed control state is 1 (indicating that it is in control state), the control speed target value is limited by the winning speed control request in the control request arbitration strategy, and the maximum limit torque is limited by the winning positive torque limit request in the positive limit arbitration strategy; the minimum limit torque is 0.

[0079] Example 2

[0080] See Figure 8 As shown, an embodiment of the present invention provides a power domain controller for receiving a request from an external controller, which includes at least one processing unit, a storage unit, and a bus unit. The bus unit of the power domain controller connects the storage unit and the processing unit. The storage unit stores a computer program.
